Theory of Machine Two pulleys of radii r₁ and r₂ and at distance x apart are connected by means of a cross belt drive. The length of the belt is π (r₁ + r₂) + [(r₁ + r₂)²/x] + 2x π (r₁ - r₂) + [(r₁ - r₂)²/x] + 2x π (r₁ - r₂) + [(r₁ + r₂)²/x] + 2x π (r₁ + r₂) + [(r₁ - r₂)²/x] + 2x π (r₁ + r₂) + [(r₁ + r₂)²/x] + 2x π (r₁ - r₂) + [(r₁ - r₂)²/x] + 2x π (r₁ - r₂) + [(r₁ + r₂)²/x] + 2x π (r₁ + r₂) + [(r₁ - r₂)²/x] + 2x ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The rotating shafts tend to vibrate violently at whirling speeds because Resonance is caused due to the heavy mass of the rotor The system is unbalanced The shafts are rotating at very high speeds Bearing centre line coincides with the axis Resonance is caused due to the heavy mass of the rotor The system is unbalanced The shafts are rotating at very high speeds Bearing centre line coincides with the axis ANSWER DOWNLOAD EXAMIANS APP
